I had mixed emotions with this product, I liked it, then hated it, then was fine with it overall. I was in dire need of a replacement down pipe after I bought my used 93 VR-4. I had to commit to installing this pipe because the OEM unit was falling apart and clogging the rearmost catalytic converter. Other than having to notch my subframe to fit this down pipe, it was a piece of cake to install. All my turbo and exhaust flange hardware were not seized. In the end, it's doing what it was designed to do and the oil pan was not getting heated with gasses from a massive exhaust leak. I did like the 2 O2 sensor bungs (with plugs) that are on the item.
